information about installing the 4-colour-ribbon cassette you will find inchapter 6 colour option.
it is recommended to use only original ribbon cassettes (part numbers in appendix h) put out by our company. using other ribbons will void your warranty.
never manually move the print head fully to the right hand stop (you could change the way of the paper output).

3. lift the top cover to gain access to the ribbon cassette mountings. the print head will move to the correct position, aligned with the cut-out in the paper guide plate to facilitate the installation of the ribbon cassette.
4. remove any excess slack by turning the green knob on the ribbon cassette clockwise. move the ribbon feed guide to the position indicated on the plastic cover of the cassette.

5. position the lower mounting pin (a) on the guide to the right. slide the cassette downward. in this position, the green ribbon feed guide touches the green plastic clip.

6. move the cassette toward you until you hear a click on both sides. swing the ribbon underneath the print head for the final click. the audible clicks indicate that the mounting pins have engaged properly.

when installed correctly the ribbon cassette has a sloping position.

7. move the print head back and forth to settle the ribbon in the correct position.
8. if necessary remove excess ribbon slack by turning the green knob clockwise.
